Title: Radar control information processor and device for creating data base for radar control
Inventor: EBINUMA YASUO
IPC: G01S13/91
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the oversight of airplanes in the direction of a radio wave reflecting body by a device which suppresses the occurrence of false images on the display of radar equipment. SOLUTION: The positional of an airplane which becomes the cause of a false image is registered in an area data base 32 as an false image causing area. A false image data detecting section 34 reads the position data of control data inputted from a received-data pre-processor 20 and identifies whether or not the control data are contained in the false image causing area. When the control data are contained in the false image causing area, the detecting section 34 searches the area for such control data that have the same identification code as the control data has in the same scan and, when the section 34 detects the control data, the section 34 identifies the control data as a false image. When such a constitution is used, airplanes existing in the direction of a radio wave reflecting target can be detected, because radar detection can be performed even in the direction.

Title: Optical disk apparatus
Inventor: TACHIBANA KAORU
IPC: G11B7/00
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain an optical disk apparatus by which high-density recorded data is reproduced surely by a method wherein a low-frequency noise is removed from a reproduced signal, a lost low-frequency component is reproduced, a slice level or a DC level is made variable and binarized in such a way that a duty ratio becomes a prescribed value. SOLUTION: An HPF 12 removes a low-frequency noise from a reproduced signal RF. A comparison circuit 13 receives the output signal RF1 of the HPF 12 via an addition circuit 14 so as to binariezethe signal RF1. An LPF 15 suppresses a high-frequency component from the output signal of the circuit 13 so as to be fed back to the circuit 14. The circuit 14 adds the signal LPF1 to the signal RF1 so as to reproduce the low-frequency component of the spoiled signal RF. A comparison circuit 17 binarizes a reproduced signal RF2 from the circuit 14 so as to generate reproduced data D2 from the signal RF2. A duty-ratio detection circuit 18 changes an output signal level according to the duty ratio of the data D2 so as to be output as the slice level of the circuit 17. Thereby, even when the DC level of the signal RF is shifted, the edge of the data D2 is held at a correct timing.

Filed: 1984-11-27
Abstract: PURPOSE:To prevent the repeated operation of an alarming device by continuing alarming for a preset time of period when the distance up to an obstacle goes below preset distance and an alarm is given once and subsequently even when the distance up to the obstacle is increased slightly further than the preset distance. CONSTITUTION:The distance up to an obstacle is detected by a sensor 13a and the detection signal is converted to a voltage signal by a processing circuit 14a. This voltage signal becomes lower than the reference voltage of an op amplifier 15a. In other words, when the distance up to the obstacle becomes lower than the preset distance, the op amplifier 15a output a signal. As a result, a light emitting diode 65a emits light and makes a display and operates a timer 30a. The timer 30a issues an output signal only for a fixed period of time and operates an alarming device 40. Once the alarming device 40 has been operated, the timer 30a operates the alarming device 40 for a fixed period of time. Then, even when the distance up to the obstacle is varied slightly approximately for the preset distance, the alarming device 40 does not perform the repeated operation.

Title: Bath boiler with hot water heater adapted to compute amount of remaining water
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/46
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To shorten automatically hot water filling operation time by a method wherein an additional boiling operation for computation is stopped when the temperature of hot water rises by the maximum rising temperature value set and thereafter, the hot water is fed into a bathtub from the hot water supply side until reaching a set amount of water at a temperature that allows the temperature of the bathtub to reach a set temperature when the feeding of hot water ends to the set amount. SOLUTION: Heat is added from a bath-side heating means 11 for heating the remaining water in a bathtub 43 by an additional boiling and the amount of the remaining water is computed based on the heat supplied and a rising temperature when the temperature rises by a specified value. In this process, a control section stops the remaining boiling operation for computation when the temperature rises by a specified maximum rising temperature value set. Thereafter, hot water is fed into the bathtub 43 from the hot water supply side until reaching a set amount of water at a temperature that allows the temperature of the bathtub 43 to reach a set temperature finally when the feed of hot water ends to the set amount of water.  This enables further raising of the temperature of the remaining water while feeding hot water from the side of a hot water heater with a higher capacity thereby shortening automatically hot water feeding operation time.

Abstract: PURPOSE:To stabilize attitude even when a pressure regulating valve becomes unusual in operation by enclosing fluid pressure within a suspension device when the pressure regulating valve becomes unusual in operation, and equalizing fluid pressure within a pair of suspension devices simultaneously in the title device controlling attitude by means of car height adjustment. CONSTITUTION:Unusual conditions of pressure regulating valves 20a-20d are detected by the difference between the actual output pressure Ps outputted from a pressure sensor 40 and the output fluid pressure Pg outputted from a controller 30 so as to let enclosing command S1 and S2 be outputted to an unloader valve 63 and a cut valve 64. This causes both the unloader valve 63 and the cut valve 64 to be actuated so as to enclose fluid pressure within each suspension unit 10a-10d. Communication commands R1 and R2 are outputted to cut valves 71 and 72 thereafter so as to let right and left suspension units 10a-10d be communicated through communication passages 54 and 55. Owing to this constitution, each pressure chamber 14 is equalized in pressure so as to make car height equal at the right and left sides, thereby enabling the stability in attitude to be improved.
